IMPROVEMENT lN JELLVGLASSS.

Specification forming part of Letters Patent No. 137,995, dated April 15, 1873; application tiled June 27, 1870.

To all whom it may concern:

Be it known that I, THEODOE A. ZELL- ERS, of East Birmingham, State of Pennsylvania, have invented an Improvement in J elly-Glasses, of which the following is a speciication:

My invention relates to the manufacture of jelly glasses or tumblers; and it consists in s0 forming the mouth of the glass that a diskshaped cover may be used, the upper surface of which will not rise above the edge of the glass.

My invention is illustrated by the accompanying dra-wing, in which Figure 1 is a vertical sectional view of the glass without its cap Fig. 2, a like view of the glass and its cap, the latter being shown as secured in place by means of an elastic rubber ring 5 and Fig. 3 is a perspective view of the glass complete.

I form the mouth of my glass with a recess or rabbet on the inside, as shown at a, such recess being designed'for the reception of the cover, which, for the purpose of inspecting the contents of the glass, I prefer to make of some transparent substance. In order to secure accurate contact between the edge of the cover and the walls of the tumbler I prefer to press my tumbler in molds, and use it in the condition substantially in which it leaves the molds, without subjecting it to the ordinary iinishing processes that are applied to drinking-vessels. If subjected to these nishing processes the mouth will be unequally contracted or expanded, and to a greater or less extent will lose its circular character 5 and in that event it may become necessary' to use a rubbtr band to hold the cover to its seat. Such a band is shown at d. Being of smaller diameter than the mouth of the tumbler, it will, when stretched over the edge of the glass, embrace both the side of the tumbler and the upper edge of the cover, as shown. When, however, the cover and the tumbler'are made to lit each other accurately, the elastic binding-band may be dispensed with, since the cover will be held to its seat with sufficient firmness by mere frietional contact with the walls of the glass.

To facilitate the removal ofthe cover I cut away a small part of the vertical rim of the glass, as shown at e, which permits the point of a knife or any other instrument to be passed under the edge ofthe cover.

What I claim as my invention is- 1. A jelly glass or tumbler provided with a recess or rabbet around the inside of its mouth to receive the edge of the cap or cover, as set forth.

2. In combination with the rabbet on the inside ofthe mouth of a jelly-glass, the break c, or its equivalent, made in the rim of the glass to facilitate the removal of the cover.

In testimony whereof I, the said THEODOR A. ZELLERs, have hereunto set my hand.
